Circle Segments Secants and Tangents

Which of the following terms refers to the region bounded by two radii and the minor arc they determine?

• secant segment

• sector of a circle

• segment of a circle

• tangent segment

What is the process in finding the measure of an angle formed by secants intersecting inside the circle?

• one-half the sum of the measures of the arc intercepted by the angle and its vertical angle pair

• one-half the sum of the measures of the arc intercepted by the angle and its intercepted arc

• twice the sum of the measures of the arc intercepted by the angle and its vertical angle pair

• twice the sum of the measures of the arc intercepted by the angle and its intercepted arc

If two chords intersect each other inside a circle, then the products of their segments are equal. What theorem corresponds to this statement?

• Radius-Tangent

• Intersecting Chords/Two-Intersecting Chords

• Perpendicular Chords

• Secant-Tangent

If two secant segments are drawn to a circle from an exterior point, then the product of the measures of one secant segment and its external secant segment is equal to the product of the measures of the other secant segment and its external secant segment. Which of the following theorem corresponds to the statement?

• Radius-Tangent

• Intersecting Chords/Two-Intersecting Chords

• Intersecting Secants/Secant-Secant

• Intersecting Secant-Tangent

How would you find the measure of the angle formed by two secants intersecting outside the circle?

• twice the difference of the two intercepted arcs

• thrice the difference of the two intercepted arcs

• one-half the difference of the two intercepted arcs

• one-third the difference of the two intercepted arcs

It is the point of intersection of the tangent line and the circle.

• Point of Tangency

• Radius

• Circle

• Tangent

The region bounded by an arc and its chord.

• Arc Length

• Segment of a circle

• Sector of a circle

• Tangent

Two segments tangent to a circle from a point in the exterior of the circle are congruent.

• TRUE

• FALSE

If a tangent and a secant intersect in the exterior of a circle, then the square of the length of the tangent segment is equal to the product of the lengths of the secant segment and its external part.

• TRUE

• FALSE

TRUE of FALSE: A tangent line intersects a circle at exactly two points.

• True

• False
